(1) Another program may be editing the same file.
If this is the case, be careful not to end up with two
different instances of the same file when making changes.
Quit, or continue with caution.

(2) An edit session for this file crashed.
If this is the case, use ":recover" or "vim -r /etc/localdomains"
to recover the changes (see ":help recovery").
If you did this already, delete the swap file "/etc/.localdomains.swp"
to avoid this message.

I was basically editing the local and remote as i have a customer who has their own exchange server and the local PHP send was leaving messages in the main account.
